Agenda

1. Make electro/chemically competent cells
2. Transform and plate R0051
3. Make more DD R0051
4. Redo R0051.B0034 ligation
5. DD I14032.B0034 and put it into pSB1AC3 as a blank vector
6. Run Polystyrene binding efficiency assay

Colony Count of last night's transformations

Making Electrochemically competent cells

Using BL-21 (for higher protein expression) Followed TK's OWW protocol.

DD I14032.B0034 Mixture

• Need to redo all I14032.B0034 digestions because it was purified using the wrong kit. Need QIAGEN Nucleotide Removal Kit (insert is 70 long)

For blank (control) vector:
5 µL I14032.B0034 #4 (225.7 ng/µL)

1 µL EcoRI

1 µL PstI

0.5 µL BSA

5 µL NEB Buffer 3

37.5 µL H20

For 3A assembly with CPX:
5 µL I14032.B0034 #4 (225.7 ng/µL)

1 µL EcoRI

1 µL SpeI

0.5 µL BSA

5 µL NEB Buffer 2

37.5 µL H20

put into 37C at 12:15 PM

For ligation in 1AC3:
37 µL F2620+B0034 (27.0 ng/µL, blue label says pure 3A pSB3k3 from XL-1)

1 µL EcoRI

1 µL SpeI

0.5 µL BSA

5 µL NEB Buffer 2

5.5 µL H20

put into 37C at 5:40 PM
